Trivial pcb with curved trace (infosec.pub)

I’m replacing a trivial pcb in a battery pack for a small fan. It’s 6V (4xAA) with a SPST top left and a USB socket top right. But why on earth would the power line on the pcb follow that curved path? There are no other components, just the 2 ends of the battery pack and a plastic housing.

Maybe just ‘because you can’?

Ha, never thought of that. Wonder what the current is—less than what some AAs can source. Guess I’d better not find out :)
